I'm about to start the wiring for my tail lights on my 64 C30 flat-bed. All I have currently is the original wires that run down the frame rail (good shape) that have been cut clean about 2/3 of the way back. I'm thinking of going to the local u-pull it, and getting a harness from a later model truck with the removable plug set up, so that I can get the trailer wire interface plug that goes inline. Am I all wrong in thinking this would be the best way to do it? I can do basic wiring and such, but this just seems like it would be the easiest/cleanest solution....??? What do you guys think?

It seems to me the other option would to be to make or find a wiring harness for that truck. You would still have to tap into the harness to wire the trailer. That could be quite a mess by the time you get done.
If you can find a harness and make it work, that might make a nice clean instillation.

Thanks Jim, that's what I was thinking....I just didn't know if maybe there was a better option....now I just need to find a suitable donor. I'm thinking a 90's vintage p/u would be new enough to have the integrated plug for the in-line trailer wire adaptor. Ahhh.....now I have another reason to go to the yard!

Sounds like a good plan to me. Solder your connections and cover with shrink tubing.

You'll end up with a lot of unused wires- - - -backup lights, clearance lights, gas gauge, fuel pump, etc. How about getting a universal trailer wiring kit? It will come with color-coded wires and it can be adapted to whatever lighting system you've got already (if any) or some kits come with the tail lights included.

Well I finally got a chance to go to the "yard" yesterday, and found a perfect donor vehicle. It was a 93 Chevy p/u that someone had already added the inline trailer wire adaptor to. It will be perfect! No extra wires except a back-up light wire, and I am going to utilize that as well. For anyone needing a tail light harness, this year truck (93) works out well, as it does not have multiple wires going to multiple bulbs.....just three wires, like our old rigs have. (well 4 including the back-up light)......easy to wire up!

Kerry,
Thanks for the tip.
Will you be using electric brakes on the trailer?
Just wondering how you'd handle that.

I was thinking along the same lines of using the GM trailer wiring and socket. I'll most likely just splice onto existing wires. Then I'd just run the brake wire next to original harness until I got to the new trailer harness.
